[jboss-user] [JBoss Seam] - automatic persitence on RENDER_RESPONSE

[christophe.laumond]

Hi,

I have something like


  | @Entity
  | public class Question implements java.io.Serializable {
  | 
  | @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "question")
  | 	public Set<Answer> getAnswers() {
  | 		return this.answers;
  | 	}
  | 

Before rendering I add Answer instance to the above Set but I don't want to persist them, I just need them in order to retrieve value fromt the UI and according to the value i will persist some of them and discard some others.

But on the render response event I got the following stacktrace :

anonymous wrote : 
  | 2006-09-28 14:07:53,984 DEBUG [org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener] committing transaction after phase: RENDER_RESPONSE(6)
  | 2006-09-28 14:07:53,984 DEBUG [org.jboss.seam.util.Naming] JNDI InitialContext properties:{java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory, java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces}
  | 2006-09-28 14:07:53,984 DEBUG [org.hibernate.event.def.AbstractFlushingEventListener] processing flush-time cascades
  | 

and all the Answer instances are persisted !

It looks like method like save() or update() are called automatically during this phase.

I would like to prevent this and understand why this happens.

Is this related to my faces-config file lifcycle tag :

anonymous wrote : 
  |     
  |         <phase-listener>org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListener</phase-listener>
  |     
  | 

thanks in advance for your feedback

Regards,
Christophe
